Nearly one million doses of the canine influenza vaccine have been given, now the USDA has granted it a full license.

The vaccine “Nobivac Canine Flu H3N8” was given a conditional license last year and with the growing concern over canine influenza, it has become a regular vaccination regimen for many dog owners.

With the dogs vaccinated studies have shown the vaccine has been successful in reducing signs, severity and spread of CIV infection, while also lowering the rate and severity of lung lesions. The USDA also says that it has shown to be well-tolerated in the dogs.

CIV is a highly contagious respiratory disease in dogs caused by influenza A virus, H3N8. Veterinarians recommend the vaccination for dogs that are often in very social situations.

“In general, any dog that is in a closed room with other dogs for at least six hours or more can be considered at risk, particularly those that are boarded frequently, go to dog shows, dog day care and training classes, or are in shelters,” said Dr. Ronald D. Schultz, professor and chair of Department of Pathobiological Sciences, School of Veterinary Medicine, University of Wisconsin-Madison.

“Other dogs that may be at risk include those in rescue groups and those that travel with families, particularly to endemic areas, are housed in breeder facilities or belong to animal healthcare personnel,” continued Crawford.

Cases of canine influenza have been identified in 33 states and the District of Columbia. During the 2009-2010 flu season, there were outbreaks in several states including here in Colorado
